Viscous spreading: evolution of the radial width of an unperturbed, initially very narrow and very dense ring (as in Lithwick & Chiang 2007). The red crosses indicate the ring’s full width at half maximum measured at different epochs. The green curve gives the theoretical behaviour in Δ = Δ0(1 + C.t1/3), for the best-fit value C = 0.13.
